The electric hoist of climbing frame has changed a lot with the optimization of electric drive and control. With the combination of mechanical and electronic skills, the updating and development of hydraulic technology, microelectronic technology, computer technology, and power electronic technology have brought great changes to the intelligentization and automation of climbing frame electric hoist. At present, in terms of the development of the electric hoist in the domestic market, these are the main directions: first, most of the current electric hoists on the market are new organizations. The motor is the driving part of the electric hoist of the climbing frame, and the reducer is the main part of the control transmission organization of the electric hoist of the climbing frame. The brake is also the safe control component of the electric hoist of the climbing frame. Most of the organizations of the electric hoist of the climbing frame are "three in one" "The organization is to integrate the driving parts, transmission parts and braking parts of the electric hoist of the climbing frame into one, so that the overall product structure is compact and beautiful, and the matching is suitable for a wide range of industries. The second point is the use of flexible organization. Electric drives are mechanical drives for a long time, and most of the electric drives have the effect of a certain amount of sudden load method known as a drive to accelerate Yin Yin. At present, this kind of launching theory is basically used in the design of lifting transportation in China. The use of flexible components-hydraulic couplings has fundamentally broken through this situation. The use of hydraulic couplings not only eliminates the impact caused by the overload and reverse direction of the motor and tissue, but even the normal start. The inertial force is also very small, and the engine is very stable. The dynamic design method of the hydraulic coupling is based on the combination of theoretical calculation and analysis of the measured results, which has achieved a great improvement. This development is a great compensation and improvement compared to the original accounting system for rigid body mechanics accounting. The third point is to reflect the standardization of transmission and control system planning. Follow the new national standards. When lifting and transporting at the operation level above M5, the speed control planning of electric control must be carried out before the lifting parts are lifted and the brakes are lowered. At the same time, in order to optimize and improve the electric control lifting organization For the functions in the running process, the method of wireless remote control on the ground and the control of the ground and the driver's cab were selected; the common climbing electric hoist in the project will use special equipment. For example, non-touch-sensitive travel switches or fault diagnosis display devices.
